Hate to revive an old thread but I ran nPDF on my CX CAS and it said I can now view .pdf, .html, etc files. Only issue I am having is getting .pdf files onto my calculator. I'm using the TI-Nspire CX CAS Student Software on my laptop and it tells me that .pdf files are not supported. I tried to change the file name to "filename.pdf.tns" but the software turns it into "filename.pdf.tns.pdf". I'm a newb when it comes to these things, but I am running 4.2 if that helps at all, and I do have Ndless 4.2cascx running on my calculator.  ??? ???
Thanks!

---Don't know if it makes a difference but I am also running Windows 10
*****UPDATE: I got it working. Well, somewhat. My PDF is 16 pages long and about halfway through the screen goes white and shows nothing... Hmmmmm....

Ctrl Tab

I don't know if npdf 0.4b is maintained by anyone here. But I switched to this version.

To "go to page," the hotkey was previously "ctrl + g," now it is "ctrl + tab."

The "goto function" is working well and consistently. But since you are hitting "tab," the cursor jumps out of the textbox where you should type the page you want.

Just a small gripe.

The only reason I looked for a newer version after using critor's for a good while, is the "goto function" was inconsistent. Sometimes it would appear, sometimes I would have to close the pdf and reopen.



Oh and for those having "white page" issues, I have found a workaround that works sometimes. Reopen the pdf, use "goto" select a page near where you want to go, and then it seems to work.

It seems like you get white pages after browsing several consecutive pages, so going 5 pages in can result in white page. It looks like the ram is maybe getting full and it doesn't dump old pages out of the memory.

Edit (Eeems): Merged double post.

Hello all!

I'm with 4.2 SO and already have de ndless and the npdf 0.4b . I'trs all been succesfully installed, but the problem comes when I try to send the documents to the calculator. The computer link recognises de .pdf file and don't let me tranfer the documents. All of you just change the name of the document for document.pdf.tns but in my case it only changes the name and the computer link still recognises that it's a pdf file (it appears documents.pdf.tns.pdf automatically). What should I do to fix this?

thanks, waiting for your answer.

It seems I've been able to fix the blank/white page issue. muPDF was set for unlimited memory allocation(FZ_STORE) and this caused some issues with larger documents. I've changed FZ_STORE to 16MB and it seems to play nicely now. All of the PDFs that gave me this issue seem to be fine now.

Attached is the tns for the patched version. I've also submitted a pull request on the GitHub for the project.

Please let me know if this works for you! Thanks

I thought I requested notifications for this thread, but I haven't received any. Anyway, I'll try to check this more frequently.

@sumpm1: That should be easy  to fix by adding one line, I will try to fix it by tomorrow.
@fgc2: This is usually an issue for Windows users, I think you have to change the settings in Windows Explorer (or whatever it is now) to show file extensions. Then you can replace the .pdf with .tns.
@krytikul: When I started this project I was having some issues (I don't remember what) with the FZ_STORE value and ended up setting it to unlimited. Hopefully it works, I will test the pull request.

Guys, I'm still on OS 3.9.1, now that Ndless is available also for the last 4.4 version it's time to update it.
Following the guide I can choose between 4.0.3, 4.2.0 and 4.4.0 version of the OS, anyone has tested the last available nPDF 0.5b with these?
Or @Legimet is planning an update of the .tns? On the Github page I see the last edit of the project is dated 7 months ago..

nPDF should work on OS 4.4, since it doesn't use any custom syscalls. I am planning an update at some point, but don't currently have the time.

Just wanted to say that nPDF works on OS 4.4 just fine.

It "works" on classic, but generally runs out of memory so it's not very usable. You can try it, though.

Thanks  :) .
Would memory optimisation be possible in the future?
Like lower picture resolution, or loading only one page at once?

I'm not really sure, I'll have to check.
